WAGON-BRAKE.

SPECIFICATICIT forming part of Letters Patent 110,632,765, datedSeptember 12, 1899.

Application filed October 25,1898- To (all whom it may 001mm.-

Be it known that 1, CHARLES E. SrETsoN, a citizen of the United Statesof America, residing at Allegheny, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inWagon and Carriage Brakes, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to certain new and useful improvements inwagon-brakes.

The object of my invention is to provide a brake which will operate onthe backward movement of a team of horses.

A further object of my invention is to provide a brake of this characterwhich can be operated by the driver of a vehicle as well as the team ofhorses or operated independently by either.

Briefly described, my invention consists of a cable, rope, chain, orother suitable means which is connected at one end to the collars of theharness and which operates the brakeshaft carrying the brake-shoes.

My invention finally consists in the novel combination and arrangementof parts hereinafter more fully described and particularly pointed outin the claims.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, in whichlike numerals of reference indicate corresponding parts throughout theseveral views thereof, and in which Figure 1 is a side view, partly insection, of my improved brake as attached to the wagon. Fig. 2 is aperspective view of my improved brake. Fig. 3 is a perspective view ofthe washer, which is secured to the pole of the wagon. Fig. 4 is aperspective View of'the keeper with the securing-pin for releasing thebrake-shoes pivotally secured therein.

Referring to the drawings by referencenumerals, 1 indicates the body ofthe wagon, having the axles 2, (only one shown,) the pillow-blocks 3therefor, wheels 4, and pole 5.

6 indicates the operating rope or cable, by which the brake-shoes 7 areoperated by the horses. This rope or cable is secured to the pole-chains8, as at 9, and operating through the end of the pole 5 on thepulley-wheel 10, which is secured therein, and on the under- Seiial No.694,500. (No model.)

neath face of the pole through the guides 11, in a portion of the axleand over the pulley 12, mounted in the upper end of the lever-rod 14.This lever-rod 14 is rigidly secured in the brake-beam 15, as at 16. Theopposite end of the cord or cable 6 is connected to the hand operatingbrake-lever 17, as at 18. The brakebeam 15 is secured to the keepers 19,which are secured, as at 20, to the underneath face of wagon-body by anysuitable means. The ends of the brake-beam 15 have secured thereto, asat 21, a brake-shoe 7 22 indicates a pillow-block which is suitablyapertured, as at 23, to allow the cord or rope to operate therethrough.

24 indicates the hand operating-rope for the brake-shoes and is securedto the bar 17,

as at 25, and to the upper end of the leverrod 14.

For automatically releasing the brake on the forward movement of thehorses I provide a pin 26, which is pivotally secured in the keeper 27by means of the rod 28, and I secure this keeper to the underneath faceof the pole, as at 29. The pole has an oblong slot 31 formed therein toallow the play of the pin 26. I mount a doubletree 32 on the pin 26, andI secure on the doubletree or its upper face the washer 33, having anoblong slot 34 formed therein. The pin 26 extends a suitable distanceabove the washer 33 and over the slot 34, and I secure to its upper enda cable or rope 35. The opposite end of this cord or cable is secured tothe lever-rod 14. It will be readily apparent, owing to the 0blong slot36 formed in the doubletree, that on the forward movement of the horsesthe doubletree will carry the pin 26 with it, thereby pulling thelever-rod 14 forward and release the brake-shoes.

38 indicates a dog which is secured to the hand-lever 17 and whichmeshes with the rack 38 to secure the lever in the position desired.

It will be readily apparent that, owing to the pole-chains 8, which areconnected to the collars of the harness, on the backward movement of thehorses the same will pull the cord or rope 6 forward and bring thebrake-shoes into contact with the rear wheel of the vehicle, therebylocking the same. The operation of the brake-shoes has been heretoforedescribed. To operate and bring the brake-shoes into contact with therear wheels by the use of the hand-lever can be easily understood fromthe drawings.

It will be noted that various changes may be made in the details ofconstruction without departing from the general spirit of my invention.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

1. In brakes for road-vehicles brought into action by the backward pullof the draft-anipole for said vehicle, a keeper secured to theunderneath face of said pole, a pin pivotally secured to said keeper,and a cord or chain 35 connected to the upper end of said pin and to thelower end of said lever-rod, substantially as described.

2. In brakes for road-vehicles brought into action by the backward pullof the draftanimals acting through the pole-chains, the combination of apole to which the polechains are attached, guides secured to theunderneath face of said pole, a brake-beam suitably supported from thebody of the Vehicle, a brake-shoe mounted on each end of saidbrake-beam, a lever-rod connected to said brake-beam centrally thereof,a pulley mounted in the upper end of said lever-rod, a brake-leverpivotally supported from the bottom of the vehicle-body, and a cord orchain connected at its one end to said polechains and passing throughthe guides on the pole and over the pulley on the lever-rod with itsother end attached to said brakelever, substantially as described.

3. In a brake of the class described, the combination of a pole with thepole-chains attached to the free end thereof, guides secured to theunderneath face of said pole, a keeper also secured to the underneathface of said pole, a pin pivotally secured in said keeper and extendingupwardly through said pole and its doubletree, a brake-beam, abrake-shoe secured to each end of said brake= beam, a'lever-rodconnected to the brakebeam, a brake-lever, a cord-or chain connectingthe pole-chains, the lever-rod and the brake-lever, and a cord or chainconnecting the lever-rod with the pivoted pin extending through thepole, substantially as described.

4. In a brake of the class described, the combination with the pole of avehicle and its pole-chains attached to the free end thereof, of abrake-beam suitably supported from the body of a vehicle, brake-shoesar-- ranged on the ends of said brake-beam, a brake-lever, means forholding said brakelever in the desired position, and means connectingthe pole-chains with the brake-beam and the brake-lever to actuate thebrakebeam and brake-shoes by the backward pull of the draft-animalsacting through the polechains, substantially as described.

5. In a brake of the class described, the

combination of a brake-beam, a lever-rod centrally connected to saidbrake-beam, brake-shoes secured to each end of said brake-beam, a pulleymounted in the upper end of the lever-rod, a pole with pole-chainssecured to its free end, a pulley arranged in said pole near its freeend, guides secured to the underneath face of said pole, a brakeleverpivotally attached to the body of the vehicle, means for holding saidbrake-lever in the desired position, a cord or chain having its one endsecured to said pole-chains and engaging said pulley and guides on thepole and the pulley on the lever-rod, with its opposite end attached tosaid brake-lever, a keeper secured to the underneath face of the pole, apin pivotally secured in said keeper and passing upward through thepole, a cord or chain connecting said pin with the leverrod, and aseparate cord or chain connecting said lever-rod and the brake-lever,substantially as described.

In testimony whereof I aflix my signature in the presence of twowitnesses.
